Overheating XF S Pak Ute - or not?
My XF ute is being a pain .....
Last winter, I had a warmer than normal thermostat installed, as I was having start up probs. She ran fine. The other day, (33 degrees) the temp gauge went through the roof (S pak dash). Checked radiator, visually fine. Bored holes in thermostat. Idled in Park for ages - temp fine. Go for a drive - through the roof. Back to mechanics. New triple core radiator - idled through a 1/4 tank of petrol (thanks guys) in the sun on a 26 degree day. Temp fine. Drove home, gauge gradually crept up to around 8 bar mark before I got her home.
Nursed her to work this morning - cold morning, gauge crept up to 5 bars.
Do you people reckon it's the gauges, or do you think I am actually running too hot? The top hose off the radiator is extremely hot, but the bottom one seems to be just on the hot side of warm (do I make sense?!)
When she's indicating hot, the volts are indicated a bit low, and oil pressure is indicated very low.
And what do I look for when I'm driving to let me know I am REALLY overheating?
